Why do heating boilers use softened water equipment? Are there any advantages?

In the north, Especially during the winter heating period, Boiler heating has become common, Type such as steam boiler or hot water boiler, Gas boilers and many other kinds. No matter what type of boiler, The feed or supplementary water of the boiler needs to be treated twice by the softened water equipment.

Because the raw water of the boiler feed water may contain impurities: Suspended matter, colloid, Organic matter, Inorganic salt, Heavy metal ion, And dissolved gases. This water (The main form of scale is calcium, Magnesium ion) Without any treatment, Once inside the boiler, Will cause harm, Suspended matter, colloid, When inorganic salt is heated or exceeds its saturation concentration, It will settle out, sludging, scale, The heat transfer efficiency and water circulation of boiler are greatly affected, Fuel waste, The heating surface is damaged, Boiler output decline, Increase of cleaning.

Water softening equipment is to remove calcium from low water, Magnesium ion content, Make the water quality reach the boiler inlet water quality standard. Operation principle of softened water equipment, When containing calcium, Magnesium ions pass through the sodium ion exchanger in water, Calcium in water, Magnesium ions are bound to the exchanger, The sodium ions of the exchanger itself are drained into the water in an equivalent amount, This process is called raw water softening; Sodium resin failure to change to calcium magnesium type, The resin is usually restored to its original sodium form by contact with a salt solution, This process is called regeneration, malacia, The recycling cycle achieves the purpose of raw water treatment.
